Renal Impairment
Pharmacokinetics have not been studied in patients with renal or hepatic insufficiency
Administration
PEG/electrolyte Solution Preparation
- Prepare solution by emptying contents of 1 pouch A and 1 pouch B into a suitable glass container (or the container provided) and adding to the container 1 L lukewarm water
- Mix the solution to ensure that the ingredients are completely dissolved
- Solution can be refrigerated prior to drinking

Use with caution in patients using concomitant medications that increase the risk of electrolyte abnormalities
Use with caution in patients with severe ulcerative colitis, ileus, gastrointestinal obstruction
Patients with impaired gag reflex and patients prone to regurgitation or aspiration should be observed during the administration
Since product contains sodium ascorbate and ascorbic acid, use with caution in patients with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency
If severe vomiting occurs, check serum electrolytes
Phenylketonurics: product contains phenylalanine
Serious arrythmias reported
Pregnancy and lactation
Pregnancy category: C
Lactation: Unknown whether distributed in breast milk, caution advised
Pregnancy categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA: Information not available.
